I remove my ubuntu 16.04 with unity desktop and install a fresh ubuntu 16.04 with gnome desktop, when I was playing dota 2 on my previous ubuntu it worked very well, however in my new ubuntu it I can't play it anymore it has alot's of lag and I don't think this is graphic problem
here is my lspci command result:

I install mesa-utlis for my intel graphic but that wont help I had still lags in the game I am wondering what is the reason I have this problem? any suggestion would be thankful.
I tried and installed lxde desktop and set my dota setting on low network however I still have lots of lag my network connection is good my Google ping is 100ms when I run intel_gpu_top command and it showed render busy 37% in the middle of game I am confused what is the problem here

If you have a compositor activated, disable it when play. The composing system will cause a lot of "lag", while playing, but the reason is the resource consuption of the composer. Also, I recommend you to install a lightweight desktop like LXDE to have better performance. However, if still want to use Gnome, try to use a lightweight desktop theme, this could contribute a little. Also, disable VSync.

In the game:

Reduce the render quality in game.

Disable the Steam overlay.

Go to Settings, Options, To Advanced options, and select I have a Low-end Network.
